accusation of magic against prophets

فَلَمَّا جَآءَهُم مُّوسَىٰ بِـَٔايَـٰتِنَا بَيِّنَـٰتٍ قَالُوا۟ مَا هَـٰذَآ إِلَّا سِحْرٌ مُّفْتَرًى وَمَا سَمِعْنَا بِهَـٰذَا فِىٓ ءَابَآئِنَا ٱلْأَوَّلِينَ

But when Moses came to them with Our signs as clear evidences, they said, "This is not except invented magic, and we have not heard of this [religion] among our forefathers."
